This letter proposes an adaptive multi-link operation (MLO) traffic-to-link allocation scheme (ATLAS) to reduce the latency of multi-link devices (MLDs) by allocating the traffic to links under enhanced distributed channel access (EDCA) uplink scenarios. A Markov chain is constructed to analyze EDCA, and the transmission probability of each access category (AC) is derived to estimate the expected access delay and queueing delay. A min-max problem is established to effectively allocate traffic of each AC to multiple links, so that the link layer delay (including the upper MAC holding delay) is minimized.
Achieving efficient uplink access and a robust performance in dense Wireless Local Area Networks (WLANs) is a critical challenge for IEEE 802.11bn (Wi-Fi 8). While uplink orthogonal frequency division multiple access (OFDMA)-based random access (UORA) enables scalable random access, its performance is highly sensitive...
Results show that joint STA-side control of contention and TXOP service is effective for low-latency Wi-Fi 7 MLO, and the proposed CIPD-BAT reduces average delay, 95th percentile delay, and jitter.
This paper studies uplink random access in a heterogeneous dual-link IEEE 802.11be network, where single-link devices (SLDs) and multi-link devices (MLDs) coexist under uplink OFDMA random access (UORA) and immediate-access multi-link operation (IAMLO). Although IAMLO can improve throughput and protect the access oppor...

Multi-link operation (MLO) with STR in IEEE 802.11be Wi-Fi 7 promises significant throughput gains but is hindered by the Block ACK Window (BAW) stall phenomenon, arising from the mandatory shared Block Acknowledgment (BA) mechanism. This letter investigates how to improve the throughput of a multi-link device (MLD) un...
Wireless LANs are one of the fastest-growing wireless technologies. IEEE 802.11 is a standard for wireless LANs. This doesn't provide Quality of Service (QoS) for multimedia applications. IEEE 802.11e enhances the QoS in wireless LANs. It introduces the Access Categories (AC) by using Enhanced Distributed Channel Acces...

Low Power Wide Area Networks (LPWANs) such as LoRa commonly adopt unslotted ALOHA for its simplicity, but the resulting throughput ceiling (0.183 frames/frame-time) limits scalability. We propose a heterogeneous multi-channel collision resolution system that partitions $M$ channels into contention channels and dedicate...
